# Changelog
## [0.4.3] - 10/30/2024
### Added
- Support for pasing ldapsearch BOF results within Havoc log files

### Changed
- Parsers now can inherit from the `LdapSearchBofParser` (since support for other C2s usually still relies on the same BOF) to cut down on code copypasta
- The `GenericParser` class (used to parse local group memberships, session data) is now called from main parsers (`LdapSearchBofParser`, `HavocParser`, etc.) to prevent each logfile from being opened, read, formatted, and parsed twice (each file is now read once and just parsed twice, once for LDAP objects and once for local objects)

## [0.4.2] - 10/24/2024
### Fixed
- Addressed [#12](https://github.com/coffeegist/bofhound/issues/12), an issue with duplicate trusted domain objects

BOFHound is an offline BloodHound ingestor and LDAP result parser compatible with TrustedSec's [ldapsearch BOF](https://github.com/trustedsec/CS-Situational-Awareness-BOF), the Python adaptation, [pyldapsearch](https://github.com/fortalice/pyldapsearch) and Brute Ratel's [LDAP Sentinel](https://bruteratel.com/tabs/commander/badgers/#ldapsentinel).
BOFHound is an offline BloodHound ingestor and LDAP result parser compatible with TrustedSec's [ldapsearch BOF](https://github.com/trustedsec/CS-Situational-Awareness-BOF), the Python adaptation, [pyldapsearch](https://github.com/fortalice/pyldapsearch) and Brute Ratel's [LDAP Sentinel](https://bruteratel.com/tabs/commander/badgers/#ldapsentinel). ldapsearch BOF logs can also be parsed from [Havoc](https://github.com/HavocFramework/Havoc) logs.

By parsing log files generated by the aforementioned tools, BOFHound allows operators to utilize BloodHound's beloved interface while maintaining full control over the LDAP queries being run and the spped at which they are executed. This leaves room for operator discretion to account for potential honeypot accounts, expensive LDAP query thresholds and other detection mechanisms designed with the traditional, automated BloodHound collectors in mind.

Check this [PR](https://github.com/trustedsec/CS-Situational-Awareness-BOF/pull/114) to the SA BOF repo for BOFs that collect session and local group membership data and can be parsed by BOFHound.

## Example Usage
Parse ldapseach BOF results from Cobalt Strike logs (`/opt/cobaltstrike/logs` by default) to /data/
```
bofhound -o /data/
```

Parse pyldapsearch logs and only include all properties (vs only common properties)
Parse pyldapsearch logs and only include all properties (vs other property levels)
```
bofhound -i ~/.pyldapsearch/logs/ --all-properties
bofhound -i ~/.pyldapsearch/logs/ --properties-level all
```

Parse LDAP Sentinel data from BRc4 logs (will change default input path to `/opt/bruteratel/logs`)
```
bofhound --brute-ratel
bofhound --parser brc4
```

Parse Havoc loot logs (will change default input path to `/opt/havoc/data/loot`) and zip the resulting JSON files
```
bofhound --parser havoc --zip
```

# ldapsearch
Specify `*,ntsecuritydescriptor` as the attributes to return to be able to parse ACL edges. You are missing a ton of data if you don't include this in your `ldapsearch` queries!

## Required Data
#### Required Data
The following attributes are required for proper functionality:

```
samaccounttype
dn
distinguishedname
